Application filed February 4, 1907. Serial No. 355,548.

Be it known that I, KNUTE N ELsoN, a citizen of the United States, residing at Chicago,

in the county of have invented a provement in Patterns for Ornamental Posts, l

Cook and State of Illinois, certain new and useful Im- Iof which the following is a full, clear, concise,

My invention relates to patterns for making molds for casting ornamental posts,-

that is to say, po with ornamental sts whose sides are provided designs.

The object of the invention is to provide a simple, vpractical and effective construction of pattern which will allow easy and `ready removal from the mold without injuring the mold or pattern,

In accordance especially the mold. with my invention I provide a post pattern in which the ornamental sides are made movable so as to moved inwardly permit their being relatively to the frame of the post when desired, when the pattern is still in the mold. i made as usual and inwardly so as from the sand and moved as usual.

In this way .the mold is then the sides are moved withdraw them slightly then the pattern is re- As a result the preliminary removal of the ornamentation on the sides of the post pattern insures the removal of the ornamentations without interfering with the mold therefor, thus of the entire pattern permitting the removal with safety.

As a convenient arrangement for providing inwardly movable or depressible sides, I

hinge the same and provide a slide with inclined plane arrangement by which the sides can be moved in lating the and out at will by manipuslide which in turn is constructed and provided with means by which it can be operated with the pattern in position in the mold.

In the accompanying drawings, an elevation of a post pattern embodying Figure 1 my invention; Fig. 2 is a longitudinal section of the same, Figs. 3, 4, 5 and 6 are cross-sec tional views on 6-6 in Fig. 1.

lines :3*3, Lil- 4, 5-5 and passing through the post in a longitudinal direction on a diagonal of the cross section.

This casing or fr ame is provided with beads 2, 3 and 4 as desired, making the bottom and top projections of the post. The sides 5, 5 are provided with ornamental-work which appears on the sides of the finished post when cast. These sides are hinged at their adjacent edges as shown in Figs. 3 to 6 inclusive, so that they can'swing from their normal wise, it will be raised or lowered by reason of,

the inclines 9 and 10. When moved in a direction to the left, referring to Fig. 2, the slide will be lowered. to the position shown in dotted lines in said figure. The inclines 9 and 10 are desirably provided with grooves 11 and 12 in which the slide 6 works (Fig. 3) and the bridges 7 and 8 are provided with adjustable screws 13 and 14:, so that the slide 6 can be forced tightly against the sides 5, 5 to place and hold the latter iirmly in position.

The slide 6 is narrowed at its ends, as shown in Fig. 3, andthe bridges 7 and 8 provided with grooves or channels in which the narrowed portions of the slide 6 can travel to serve as guideways therefor. Between its ends the slide 6 is wider as shown in Figs. 4 and 5, and at a point nearly midway between its ends its sides are flattened at 15, 15, and at these points the sides 5, 5 are provided with projecting extensions 16, 16 between which is disposed a coil spring 17 which tends to pull said sides toward one another. At one end of the slide 6 is a handle 18 by which the slide can be engaged by the hand to move it back and forth.

In operating the device, the pattern is arranged in the condition shown in full lines in the drawings. The slide 6 is in its upper or normal position in said figures, forcing the sides 5, 5 into their outward positions. The pattern is then put in place in the mold and the sand packed around it. 13 and 14 are'unloosened if tightened, and the slide 6 they have been is moved in a IOO Then the screws .f

by said slide moves laterally to swing said side walls in and out. 3 5

4. A post pattern comprising a diagonally out longitudinal half of Aa post having hinged side portions, a slide longitudinally movable within said pattern, inclines on the slide for moving the same laterally so as to swing the 4o sides of the pattern in and out, and spring means tending to swing the sides toward each other.

5. A post pattern comprising a casing in the form of a diagonally out longitudinal 45 half of a post, said casing having side walls hinged along adjacent edges, and also having cross pieces or bridges a coil spring connected with said side walls and tending to swing the same toward one another across the pieces or 5o bridges on said casing, a longitudinally disposed slide within the casing mounted on said bridges, said slide having inclines whereby it is shift-ed laterally when moved longitudinally and Vbeing arranged to swing the side por- 55 tions ofthe casing in and out by its lateral shifting, and a handle 18 by which' the slide can be engaged and shifted.

ln witnessl whereof, I hereunto subscribe my naine this 30th day of January, A. D. 6o 1907.

lengthwise direction by the handle 18, as a result of which it descends into a lower position as shown in dotted lines in the drawings. The hinged sides 5, 5 thereupon drop from 5 their outer position to -inner or depressed positions as shown in dotted lines being drawn inwardly or toward one another by the spring 17 as shown in Figs. 4, 5 and 6, thereby removing said sides 5 and their or- 1o namentations from contact` withI the sand. The entire pattern can then be withdrawn or removed in the usual way, and the mold will not be destroyed or injured'by the projecting portions of the ornamentations.

15 It will be understood that changes and modifications can be made without departing from the spirit of the invention.

What I claim iszv 1. A post pattern consisting of a longituzo dinal half of the post out between diagonal corners and having inwardly movable sides, and means whereby the same can be moved inwardly while the pattern is in the mold.

2. A ost pattern consisting of a longitu- 25 dinal ha f of a post cut along a plane extending between opposite corners of the post, the wall portions or' said postbeing hinged so as to swing inwardly, and ,means whereby said i wall portions can be swung inwardly while 3o the-pattern is in the mold.
